A heat exchanger assembly has a top par and a bottom part joined to the top part. At least one of the top and bottom parts defines a recess. The top and bottom parts define therebetween a passage formed in part by the recess. The passage has a first portion of the passage extending along a first side of the heat exchanger assembly; a second portion of the passage extending along a second side of the heat exchanger assembly; an inlet fluidly communicating with the first portion of the passage near a first end of the passage; and an outlet fluidly communicating with the second portion of the passage near a second end of the passage. Fluid enters the passage via the inlet, then flows in the first portion of the passage, then flows in the second portion of the passage, and then exits the passage via the outlet.

A snow groomer with touch screen controls for tensioning tracks, suspension, drive unit, accessories and other, comprising: a plurality of tracks; at least one accessory device selected in a group comprising a shovel or blade, a tiller assembly and a winch assembly; and a user interface comprising a display and a selector device for receiving commands from an operator, preferably the selector device is a device that detects a touch of an operator on the display; a control unit coupled to the user interface, in particular to the display, for sending images to be displayed to the display and receiving commands from the display which are related to the touches detected; wherein the control unit is configured to display on the display a main screen divided into a plurality of main screen portions, wherein the plurality of main screen portions are displayed together in the main screen and each in a different position in the main screen; wherein each main screen portion is configured to display an image that illustrates one or more pieces of data and/or information correlated to the tracked vehicle; the control unit is configured to detect one or more selections made by an operator, preferably on the display by means of a touch, corresponding to the type(s) of data or information that are required to be displayed in each portion of the display, and to display a main screen portion in each portion of the display, wherein each main screen portion is configured to illustrate a respective image relating to the data or information selected by the operator for said portion of the display.

A method for accelerating a vehicle from rest. The method includes receiving a mode indication indicating a launch control mode selected; receiving a brake-on indication; controlling the engine according to a launch control strategy; determining an accelerator position; for an accelerator position greater than zero, controlling the engine to: increase open a throttle valve and control the engine to limit engine torque output; receiving a brake-off indication; controlling the engine according to the standard control strategy, controlling the engine according to the standard control strategy with the braking system having been released causing the vehicle to accelerate from rest, a first rate of acceleration from rest of the vehicle being greater than a second rate of acceleration from rest of the vehicle for corresponding changes in accelerator position, the first rate corresponding to accelerating from rest after controlling the engine according to the standard and launch control strategies.

One example provides a chassis for an electric snowmobile including a battery pack. The battery pack includes a battery pack housing defining an enclosure for housing a number of battery modules for powering an electric motor of the electric snowmobile, the battery pack housing having a length extending in a longitudinal direction of the snowmobile, the battery pack housing including a bottom surface. A pair of opposing side panels extends downwardly from and along at least a portion of the length of the battery pack housing, the opposing panels and at least portions of the bottom surface of the battery pack housing together forming a rear structure extending in the longitudinal direction of the electric snowmobile.

A container, a stackable container assembly and a vehicle having a container. The container includes a container body having a top surface and a bottom surface; and a fixture assembly configured for receiving an accessory container, the fixture assembly being separately formed from and attached to the top surface, the bottom surface being configured for connecting the container to a vehicle, the bottom surface including: a tongue attached to the bottom surface, the tongue extending from the bottom surface, the tongue being configured for inserting into a first vehicle anchor fixture connected to the vehicle, and an anchor attached to the bottom surface, the anchor being configured for inserting into a second vehicle anchor fixture, the anchor including: at least one anchor lock extending parallel to the bottom surface.

An electric snowmobile that performs heat exchange with a simple structure is provided. The electric snowmobile includes a body frame, a driver's seat, an electric motor, a ski, a track mechanism, a battery, a cooling unit that cools fluid at least in accordance with outside air, a first heat exchange unit that performs heat exchange between the battery and the fluid, a second heat exchange unit that performs heat exchange between the electric motor and the fluid, a first flow path for delivering the fluid cooled in the cooling unit to the first heat exchange unit, a second flow path for delivering the fluid cooled in the cooling unit to the second heat exchange unit, and a third flow path for delivering the fluid heat-exchanged in the first heat exchange unit and the fluid heat-exchanged in the second heat exchange unit to the cooling unit.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

A heat exchanger assembly has: a front portion; a middle portion rearward of the front portion; a rear portion rearward of the middle portion, at least one of the front and rear portions being curved from the middle portion, the at least one of the front and rear portions extending below the middle portion; a top part, the top part defining at least one top recess; and a bottom part disposed below the top part and being joined to the top part, the bottom part defining at least one bottom recess. The top and bottom parts define therebetween a passage formed in part by the at least one top recess and the at least one bottom recess. The passage has an inlet and an outlet. A snowmobile having the heat exchanger assembly is also disclosed.
